Windows only: Free Windows utility D-Color customizes your Windows desktop icons, allowing you to switch your icon's text color, background color, and icon layout styles. It's a very simple, lightweight app that does just a few things, but if you're a desktop tweaker, it's a great little tool. Try swapping your icons to "Tile Icons" for a nice tweak that gives your icons a more organized stack look. D-Color is freeware, Windows only. UPDATE: The once working link to the D-Color homepage below is now redirecting elsewhere, so D-Color may be MIA.
